The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the invention. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

System 100 performs a process for determining an area where images (for objects) should be placed such that they account for a user's (for a user 102) line of sight 127 a through a transparent display apparatus 104 (e.g., a window, a heads up display (HUD), etc). Line of sight is defined herein as including all equivalent information to a line of sight and/or information capable of deriving a line of sight. For example, a line of sight may be calculated to determine image placement. Alternatively, a line of sight may include a set of processed measurements for producing a location of image placement.

System 100 includes user facing devices (or cameras) 112 a and 112 b and object facing devices (or cameras) 110 a and 110 b attached to display apparatus 104 and connected to a computing system for processing. User facing devices 112 a and 112 b identify a relative special position of the user's eyes with respect to display apparatus 104. Object facing devices 110 a and 110 b simultaneously identify an object(s) spacial position on an opposite side (i.e., from user 102) of display apparatus 104.

System 100 enables a generic pattern recognition process with respect to facial features via a user facing devices 112 a and 112 b (e.g., recognition of relative positions of anatomical features including, inter alia, eyes, ears, nose, etc.) to triangulate a relative eye position in order to infer line of sight information. System 100 may determine the angle and distance of a user's eyes/face from itself using user facing devices 112 a and 112 b via paths 115 a, 116 a, 115 b, and 116 b, respectively. The various spacial positions are used to determine a position of an image presentation on display apparatus 104 relative to viewable objects (e.g., object 108) from a perspective of user 102. Additionally or alternatively, the image presentation may include an illumination of display apparatus 104 (e.g., an image projection, an image reflection, an image hologram, etc).

System 100 includes transparent display apparatus 104 (including transparent displays 104 a and 104 b) that includes user facing devices 112 a and 112 b and object facing devices cameral 10 a and 110 b connected to a computing system for discerning a user's 102 relative eye position and for discerning an object's 108 relative position with respect to display apparatus 104. Display apparatus 104 may include any type of display apparatus including, inter alia, windows, an HUD, etc. System 100 allows image selections to be made by a relative position of a display apparatus, user, and object irrespective of an angle or geometry of the display apparatus.

System 100 includes multiple fixed user facing devices (i.e., user facing cameras 112 a and 112 b) enabling a triangulation process for determining the user's relative position. Additionally, multiple object facing devices (i.e., object facing devices 110 a and 110 b) enable a triangulation process with respect to objects such that an accurate line of sight (i.e., line of sight 127 a) may be determined. The aforementioned information may be used to determine where to display information (on display apparatus 104) relative to user 102. For example, with respect to transparent glass capable of displaying data, forward and rear facing devices (e.g., user facing devices 112 a and 112 b and object facing devices 110 a and 110 b) in combination with a computing system determine where to display data on the transparent glass such that the data appropriately overlays a scene behind the transparent display. As an example, a ship's bridge could use the aforementioned information to overlay information on landmarks, deckhands, or detected objects on its windows such that a user would have an accurate representation of where these objects are, irrespective of the user's position on the bridge. As a second example, with respect to a windshield capable of dimming in select areas, sets of forward and rear facing devices may determine which portions of a windshield should be dimmed such that bright objects may be attenuated from a user's perspective, regardless of where the user is positioned relative to the windshield.

An implementation example enabled by system 100 allows a user 102 to look through a set of windows (i.e., display apparatus 104 shaped as rounded rectangles) from two different angles (i.e., a first position illustrated in FIG. 1A and a second position illustrated in FIG. 1B). Object and user facing devices (i.e., user facing devices 112 a and 112 b and object facing devices 110 a and 110 b) interpret the locations of both user 102 and an object 108 relative to the windows (i.e., via line of sight 127 a or 127 b). Using the interpretation of the locations, an arrow 108 a may be displayed on an appropriate area of the window such that user 102 is able to view arrow 108 a overlain and accurately pointing to object 108 along line of sight 127 a or 127 b. Additionally, the forward and user facing devices may account for a vertical offset of both user 102 and object 108. Additional images related to objects may be simultaneously displayed in position relative to user 102 and respective objects.

Additionally, symbols describing relationships between objects may be enabled. Relationships may include, inter alia, a distance between two objects, etc. The following implementation example describes a process associated with symbols describing relationships between objects:

A display system installed on a crane may display information associated with a location of a lifted load relative to the ground. The display system retrieves and combines information associated with the location of the lifted load and a geometry of the ground resulting in a box (being displayed) indicating a location on the ground that the load is positioned above.

FIG. 2A illustrates a first object facing internal logic view/object image 205 of a computing apparatus for determining a line of sight between a user and an object for image placement on a transparent display apparatus, in accordance with embodiments of the present invention. Internal logic view/object image 205 illustrates a retrieved image of objects 207 and 208. An image of an object may be created using information from any type of sensor that may convey information to identify a specific position. For example, in the aforementioned implementation example, an image of an object may include a measurement of a boom angle and a length of a cable supporting a load. Additionally, note that the determination of the load-ground system as a first object, with measurements of boom angle and cable length comprising the object's key features may be “hard coded,” (i.e. the display system may be designed/configured to process a set of specific measurements without determination at runtime). Prior to, simultaneously, or subsequent to the process enabled by internal logic view/object image 205, a relative location of a user is determined. The determination of a relative position of a user is described in detail with respect to FIGS. 4A-4C, infra.

FIG. 2B illustrates a second object facing internal logic view 205 a of the computing apparatus for determining a line of sight between a user and an object for image placement on a transparent display apparatus, in accordance with embodiments of the present invention. Second internal logic view 205 a enables a process for identifying object 207 for image placement. Enhancement marker 210 includes a marker symbolic of a process for identifying object 207. Additionally, a relative angle (i.e., represented by line 212) and distance to the object facing device is determined. The distance may be determined by additional information passed by the object facing device to a processor of the computing apparatus. For example, a radar that determines a distance as well as an angle, a stereoscopic image that is processed to determine a distance of object 207. Information relating to object 207 is retrieved for image placement on a transparent a display apparatus. Additionally, a symbol or text associated with object 207 may be generated for image placement on the transparent display apparatus.

FIG. 3A illustrates a system 300 for displaying information 314 associated with an object 307 on a transparent display apparatus 310, in accordance with embodiments of the present invention. Information 314 may include any type of information associated with object 307 including, inter alia, an arrow, text (e.g., sun), an animated image of object 307, etc. Information 314 is displayed such that information 314 is located relative to a line of sight 312 between eyes of a user 308 and object 307. Line of sight 312 may be calculated from data retrieved from a user facing device 319 and an object facing device 320 in combination with a location of transparent display apparatus 310. Alternatively, user facing device 319 and object facing device 320 may be replaced by a wide field of view device 325 configured to be rotated in a direction 327 and a direction 328 such that the wide field of view device 325 is placed in a user facing device mode and an object facing device mode. The user facing device mode and the object facing device mode allow a line of sight 331 and a line of sight 332 to be calculated from data retrieved from wide field of view device 325 in combination with a location of transparent display apparatus 310.

FIG. 3B illustrates a system 400 for displaying multiple information 414 and 432 associated with an objects 407 and 422 (respectively) on a transparent display apparatus 410, in accordance with embodiments of the present invention. Information 414 and 432 may include any type of information associated with objects 407 and 422 including, inter alia, an arrow, text (e.g., sun, moon, etc), an animated image of an object, etc. Information 414 is displayed such that information 414 is located relative to a line of sight 412 a between eyes of a user 408 and object 407. Likewise, information 432 is displayed such that information 432 is located relative to a line of sight 412 b between eyes of user 408 and object 422. Line 440 between user 408 and user facing device 419, line 441 between object facing device 420 and object 407, and line 442 between object facing device or sensor 420 and object 422 each include an input to the process for displaying information 414 and 432. Line of sight 412 a and line of sight 412 b (or equivalent information) are calculated using information from both user facing device 419 and object facing device or sensor 420.

FIG. 3B illustrates transparent display apparatus 410, user facing device or sensor 419, and object facing device 420 mechanically coupled at a known location relative to each other thereby enabling one example method of calculations for placement of information 414 and 432. User facing device 419 may determine a distance by analysis of facial features or other means (e.g., sensors) that pass range information or triangulation with multiple user facing devices or sensors.

Internal logic view 455 b illustrates a process for identifying a user face, relative angle, and distance relative to a user facing device. Internal logic view 455 b illustrates logic for determining an origin of the user's line of sight (i.e., in 3D coordinates or a distance measured and location of the origin of the user's line of sight relative to a field of view), face angle, relative angle, and/or distance. A face angle is defined herein as an angle of the user's head relative to the user facing device (e.g., is the user's head turned). A relative angle is defined herein as a determination of a location of the user's eyes relative to the user facing device. A distance is defined herein as an approximate distance of the user derived from: a measurement of facial features that may factor in a face angle; a triangulation process using a plurality of devices; and/or a range sensor, etc. Data 464 a includes a symbolic representation of user's 408 relative angle with respect to user facing device 419. Data 464 b may include information used to determine an angle, face angle, and distance of the user with respect to the user facing device.

FIG. 5 illustrates an algorithm detailing a process flow enabled by system 100 of FIGS. 1A and 1B, in accordance with embodiments of the present invention. Each of the steps in the algorithm of FIG. 5 may be enabled and executed by a computer processor executing computer code. In step 500, a computing system receives an image of a user from a user facing device (or sensor). In step 502, program instructions identify key features of the image. Additionally, program instructions may determine a position of the user's eyes with respect to the user facing device on based on the key features. The key features may include facial features of the user. The facial features may include eyes of the user. In step 504, program instructions determine and analyze attributes of the key features. Determining the attributes may include, inter alia: determining an angle of the user's head with respect to the user facing device, determining a distance of the user with respect to the user facing device, etc. In step 508, program instructions receive an object image of objects. In step 509, program instructions identify a first object of the objects. In step 512, program instructions identify object key features and associated attributes of the first object.
